Preheat your oven to 400 F.
In a small bowl, combine the butter or other cooking fat, garlic, mustard, and horseradish. Mix until smooth.
¼ cup softened butter, 3 cloves garlic, 1 tablespoon of Dijon or homemade mustard, 1 tablespoon good quality or homemade horseradish
Rub the roast all over with the mixture.
3 ½ lb top sirloin roast beef
Lay the bacon pieces out flat so that they are slightly overlapping. Then place the roast on top of the bacon and wrap the pieces around the roast. If needed, use toothpicks to hold the bacon in place.
6 slices bacon
Place the roast in a roasting dish and cook at 400 F for 20 minutes.
Once the roast has been in for 20 minutes, add the wine and stock to the roasting dish. At the same time, adjust the heat to 350 F.
¾ cup red wine, 1 ¾ cups homemade beef stock
Roast for about 70 minutes, depending on how well done you like your meat. 20 minutes per pound is a good rule of thumb for a medium rare to medium well roast. There is a good reference chart included in the cookbook to know the exact roasting times of the different cuts of meat.
